In their own words
Arm Keil MDK
Arm Keil MDK is a toolchain for embedded software targeting Cortex-M and Ethos-U processors. MDK v6 supports command-line, IDE, and continuous-integration workflows across major operating systems. It includes Keil Studio extensions for Visual Studio Code, Keil μVision, Arm Compiler for Embedded, and Arm Fixed Virtual Platform models. Software packs add device and board support, middleware, components, code templates, and example projects independently of the toolchain. Keil Studio supports CMSIS workflows with an integrated debugger and extensions for creating, building, and testing embedded applications. Listed integrations include CMSIS-FreeRTOS, Keil RTX5, MDK-Middleware, IoT clients, CMSIS-DAP, ULink, and third-party debug adapters. Community is for non-commercial use. The listed MDK v6 Essential plan costs $99 a month per license; Professional costs $199 a month per license and adds Arm Virtual Hardware, functional-safety compiler tools, and legacy tools including Arm Compiler 5. Keil μVision is available only for Windows hosts.
Wing Python IDE
Wing Python IDE is a Python development environment for Windows, macOS, and Linux. Its editing and navigation tools include auto-completion, code analysis, refactoring, inline error detection, multiple keybinding styles, and project-wide navigation. Debugging features include conditional breakpoints, multi-process debugging, an interactive Debug Console, and array and dataframe viewers. Wing supports unittest, pytest, doctest, nose, and Django, and can rerun tests affected by edits using coverage information. It also supports remote work on hosts, virtual machines, containers, Raspberry Pi, AWS, and LXC/LXD clusters. Wing Pro adds AI agent development tools, integrating Claude Code through a Tasks tool and MCP servers for analysis, testing, debugging, and review. AI-assisted development may send code and prompts to the selected provider; AI configuration can be left disabled to avoid this. The free trial offers the full Pro experience for 30 days. Listed paid licenses include Wing Classic Annual at $69 a year and Wing Pro Annual at $179 a year; Pro requires a Claude Code subscription.
